5G RAN Slicing for Deterministic Traffic
2021 IEEE Wireless Communications and Networking Conference (WCNC), 2021A key aspect of 5G is the facilitation of network convergence. It enables the support of a broad range of use cases including real-time applications over the same shared network infrastructure. One major challenge in addressing the various latency requirements is the efficient sharing of resources for heterogeneous services under the presence of ...

Open source RAN slicing on POWDER
Proceedings of the 19th Annual International Conference on Mobile Systems, Applications, and Services, 2021This demonstration will showcase our efforts to develop a radio access network (RAN) slicing mechanism that is controllable via management software in an Open RAN framework. To our knowledge, our work represents the first effort that combines an open source Open RAN framework with an open source mobility stack, provides a top-to-bottom RAN application ...

Network Slicing in Heterogeneous Software-defined RANs
IEEE INFOCOM 2020 - IEEE Conference on Computer Communications, 20205G technologies promise to revolutionize mobile networks and push them to the limits of resource utilization. Besides better capacity, we also need better resource management via virtualization. End-to-end network slicing not only involves the core but also the Radio Access Network (RAN) which makes this a challenging problem.

Smart Network Slicing for Vehicular Fog-RANs
IEEE Transactions on Vehicular Technology, 2019Modern transportation systems are facing a sharp alteration since the Internet of Vehicles (IoV) has activated intense information exchange among vehicles, infrastructure, and pedestrians. Existing approaches fail in efficiently handling the heterogeneous network traffic because of the complicated network environment and dynamic vehicle density ...

A Slice-Based O-RAN Physical Layer Framework for RAN Slicing Implementation
2024 IEEE Conference on Standards for Communications and Networking (CSCN)In this study, we propose a slice-based RAN slicing framework to improve resource management in the physical layer (PHY) by leveraging O-RAN split 7.2x architecture. Although network slicing is relatively easy to implement on the core network side, the dynamic management of physical resources according to slices is quite complicated on the RAN side. In

Distributed multi-tenant RAN slicing in 5G networks
Wireless Networks, 2022International audience ; Network slicing is a promising technology in 5G networks. The key concept is to divide the physical network into multiple logical networks, that are tailored to fulfill diverse service requirements. In this paper, we propose a multi-tenant radio access network (RAN) slicing approach that enables adaptive and isolated logical ...

RAN Slicing-based Handover Scheme in HetNets
2018 IEEE 23rd International Conference on Digital Signal Processing (DSP), 2018In this paper, we propose a radio access network (RAN) slicing based handover scheme in heterogeneous networks, which provides users with better QoS of customized services during handover. Firstly, we present a hierarchical control model composed of a global controller and multiple local controllers for the heterogeneous networks, including LTE, WLAN ...

Data-Driven RAN Slicing Mechanisms for 5G and Beyond
IEEE Transactions on Network and Service Management, 2021One of the main challenges when it comes to deploying Network Slices is slicing the Radio Access Network (RAN). Indeed, managing RAN resources and sharing them among network slices is an increasingly difficult task, which needs to be properly designed.
